Extensiv Integration: your 3PL's warehouse system, your own multichannel OMS

Extensiv (formerly 3PL Central, after absorbing Skubana) runs the warehouse management behind a large network of 3PLs. The InfiPlex™ OMS sits on the brand side: it aggregates every sales channel you run, sends fulfillment-ready orders to your Extensiv-powered 3PL, and keeps inventory synced across everywhere else you sell.

  • Works With Your Extensiv 3PLNo disruption to an existing fulfillment relationship
  • Real Multichannel OMSOrders & inventory unified across every channel
  • USA-Based Support TeamOnboarding & configuration included

How it works

How the InfiPlex Extensiv integration works

If your 3PL runs its warehouse on Extensiv, InfiPlex becomes the layer that feeds it clean, aggregated orders: every sales channel you run pulls into one InfiPlex queue, fulfillment-ready orders flow to your 3PL's Extensiv system, and shipment confirmations plus inventory levels flow back — all reconciled against a single inventory pool that also covers any channel or warehouse Extensiv itself isn't involved with.

Flow diagram: Extensiv sends new orders to the InfiPlex Order Management System about every 15 minutes. InfiPlex pushes tracking numbers and real-time inventory back to Extensiv, and routes orders to Your Sales Channels, Other Warehouses / 3PLs, Other Carriers for fulfillment.

The InfiPlex Extensiv sync rail: orders ready to fulfill flow from the OMS into your 3PL's Extensiv-powered warehouse; Extensiv returns shipment confirmations and inventory levels; and InfiPlex pushes tracking out to whichever sales channel the order came from — while inventory stays reconciled across every connected channel in one pool.
